Its site EUI of 54.5 kBtu/ft² is about 16% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.1 kgCO₂e/ft² is about 12% below the group average of 5.8 kgCO₂e/ft².
At 555,264 sq ft, it is about 170% above the average floor area of 205,440 sq ft for those buildings. It was built in 1963, 23 years later than the group's average year built (1940).

What does an ENERGY STAR score of 76 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In New York City, 43% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 777 Third Avenue's 54.5 kBtu/ft² across 555,264 sq ft works out to about 30.3 billion Btu (8,869 MWh-equivalent) in 2024. Its source EUI of 115.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,068,175 kWh of electricity for the year.
